GOAD COMPANY fabricates Polypropylene tanks using state-of-the-art plastic welding equipment. Tanks are fabricated with 90° thermally formed vertical corners and pressure butt-welded vertical joints, then extrusion welded sidewall to bottom construction.  Large tanks are fabricated with Steel Structure. This steel structure can be encapsulated with polypropylene, or with clear vinyl PVC for reliable visual inspection, as pictured below.

NOTE:  FM Global Property Loss Prevention Data Sheets recommend using “noncombustible construction for all pickling and electroplating tanks, fume collection and exhaust equipment and ducts”  Of thirty plastics tested, polypropylene (PPL) was rated worst as a fire hazard. PPL has been called “diesel fuel in the solid state” (almost all hydrocarbon) and it burns with a maximum heat release rate approaching that of gasoline when burning. Temperatures up to 1093 degrees C (or 2000 degrees F) are reached, sufficient to cause steel to lose strength and buildings collapse.
